| You planted the perfect crop. You scouted it all season. You managed inputs like a pro. But if your concaves are wrong, you’re leaving thousands of dollars on the ground — every single acre, every single season. |
Every harvest season, American farmers race against the clock. Weather windows shrink. Labour is harder to find. Fuel bills keep climbing. And somewhere in the middle of all that pressure, one of the most overlooked pieces of equipment on your combine is quietly costing you money.
Your concaves.
Most farmers running stock OEM concave systems are losing 2 to 5 bushels per acre to rotor loss alone — and they don’t even know it’s happening. On a 2,000-acre soybean operation at $12 a bushel, that’s up to $120,000 walking out the back of your machine every harvest. And that’s before you count the time lost swapping concaves between crops, the dockage fees from damaged grain, or the fuel burned pushing a system that wasn’t built to handle your volume.
The Estes XPR3 Concave System was built to fix all of that — with one upgrade, once, for every crop you grow.
The Problem With Stock OEM Concaves
Standard concaves that come with your John Deere or Case IH combine were designed to be a general-purpose solution. And a general-purpose solution, on a high-production American grain farm, costs you money in ways that add up fast.
Here’s what stock concaves are doing to your operation:
- Rotor loss of 2–5 bushels per acre — every acre, every season
- Grain-on-steel threshing cracks and splits kernels, increasing dockage fees and lowering your market grade
- Crop-specific settings mean stopping, swapping covers and bands between corn, beans, and wheat — costing hours during your most critical days
- Overloaded separation sections force you to slow down ground speed, meaning fewer acres per day and more machine hours burned
- Higher fuel consumption from an inefficient threshing system fighting itself all day long
The bottom line: farmers who haven’t upgraded their concaves are financing their losses every season, while thinking their combine is performing fine. It isn’t.
Introducing the Estes XPR3 – One Concave System for Every Crop You Grow
Estes Performance Concaves has one focus: building the best-performing concave system on the market. Not combines. Not planters. Not sprayers. Just concaves — and they’ve spent years perfecting it.
The XPR3 Concave System is the flagship product, and it’s built on a simple promise that no OEM system can match:
| ONE CONCAVE. ALL CROPS. ZERO COMPROMISES. No covers. No bands. No swapping between corn, soybeans, wheat, sunflowers, milo, canola, or any other crop you grow. |
The XPR3 is compatible with John Deere S-Series, STS-Series, Case IH, New Holland, and Fendt rotor combines — covering the machines that power the majority of American large-scale grain operations.
And here’s what sets Estes apart from every other aftermarket concave option on the market: the XPR3 isn’t just a part swap. It’s a complete threshing and separation system upgrade — the only aftermarket company to offer a full system kit including the patented Xtreme Separation Grates.
How the XPR3 Works Across Every Crop You Harvest
The secret behind the XPR3’s all-crop capability is a combination of patented engineering, smarter threshing geometry, and a separation system that keeps working where stock concaves give up. Here’s how it performs across the crops you’re growing right now:
| Crop Type | Speed Benefit | Quality Benefit | Concave Change? |
| 🌽 Corn | Higher speed | Less splits | ✅ No swap |
| 🌿 Soybeans | Stop rotor loss | Award-winning clean | ✅ No swap |
| 🌾 Wheat | 20 fewer days | <1% foreign material | ✅ No swap |
| 🌻 Sunflowers | Full crop capture | Intact kernels | ✅ No swap |
| 🌱 Seed Crops | Gentle threshing | Top germination | ✅ No swap |
| 🌿 Specialty Crops | Controlled pressure | Zero compromise | ✅ No swap |
Corn — Run Faster, Thresh Harder
Corn demands capacity. With the XPR3’s 135% more threshing surface area than OEM round bars, your rotor stays full and works the crop evenly. Farmers report running corn at 1–3 MPH faster than stock — translating to up to 40 extra acres per day.
Soybeans — Stop the Rotor Loss That’s Costing You $30,000 Per Season
Soybean farmers using standard concaves lose up to $30,000 for every 1,000 acres from poor threshing and rotor loss. The XPR3’s material-on-material threshing method keeps the rotor full, threshes gently, and the Xtreme Separation Grates suspend the crop mat so every knocked-free bean escapes — instead of riding out the back as loss. Result: near-zero rotor loss and award-winning cleanliness standards that seed companies actively endorse.
Wheat — Finish Harvest 20 Days Faster
XPR3 users have reported reducing their wheat harvest window by 20 days compared to stock concaves. Faster ground speeds, no cover changes, and foreign material consistently under 1% mean cleaner grain, fewer dockage hits, and a harvest that ends before the weather turns.
Specialty & Food-Grade Crops — Gentle Enough for Your Most Valuable Acres
For white corn, seed soybeans, popcorn, or any crop where kernel integrity determines your price, the XPR3’s material-on-material threshing is the difference between a premium crop and a discounted one. Slower rotor speeds keep the thresher full and power-efficient, while the patented bar design ensures controlled, gentle separation without the grain-on-steel damage that costs you in the elevator.
The 3 Performance Pillars of the XPR3 System
| PILLAR 1 — Eliminate Rotor Loss The Xtreme Separation Grates are the only system on the market that keeps the crop mat in a suspended state after threshing. Standard wire or finger grates let the mat wrap tightly around the rotor tube, trapping knocked-free grain and running it out the back as rotor loss. The XPR3 grates use constant piercing action that keeps free grain escaping throughout the entire separation zone — virtually eliminating rotor loss on every crop you run. |
| PILLAR 2 — Superior Grain Quality Grain-on-steel contact is the enemy of grain quality. Every crack, split, and fine your concaves create costs you at the elevator in dockage fees — and costs you next season in volunteer crops. The XPR3 uses material-on-material threshing, keeping the rotor full so the crop threshes itself with controlled pressure rather than smashing against steel bars. The result is fewer cracks, cleaner samples, better germination rates for seed crops, and the ability to capture food-grade and seed premiums that stock concaves simply can’t deliver. |
| PILLAR 3 — Increased Combine Efficiency Capacity. Speed. Fuel. The XPR3 delivers on all three fronts. Farmers consistently report up to a 200% increase in capacity over OEM systems, ground speed gains of 1–3 MPH, and fuel savings of 0.9 gallons per acre. That speed increase alone — just 0.5 MPH more — means 40 extra acres per day. Across a full harvest, that’s fewer machine hours, a shorter harvest window, and a combine that reaches trade-in in better condition. |

| Operator Ease | Complex settings needed | ✅ Easier for all operators |
| Cover/Band Needed | Yes — crop-specific | ✅ None required |
| Autonomous Ready | Not optimized | ✅ Built for AI/auto combines |
The ROI Case: Does It Pay for Itself?
Let’s run the real numbers on a 2,000-acre corn and soybean operation:
| Loss Category | Estimated Annual Recovery |
| Rotor loss (3 bu/acre × 2,000 acres × $12) | $72,000+ |
| Dockage fee reduction | Up to $300,000 |
| Fuel savings (0.9 gal/acre × 2,000) | $3,600+ |
| Faster harvest (fewer machine hours) | Reduces overhead cost |
| Premium grain pricing (food-grade/seed) | Market-dependent |
| The XPR3 pays for itself — often in a single harvest season. For large-scale operations, it pays for itself many times over, every single year. |
Who Should Be Running XPR3 Concaves?
The XPR3 was built for the American farmer who demands maximum performance from every hour their combine runs. This upgrade is specifically designed for:
- Large grain operations (1,000+ acres) running John Deere or Case IH rotor combines
- Corn and soybean farmers losing money to rotor loss and grain damage every season
- Seed and food-grade crop growers where kernel quality directly determines your selling price
- Farmers dealing with labor shortages who need equipment that’s easy to set — even for less experienced operators
- Progressive operations preparing for AI-assisted and autonomous combine harvesting — the XPR3 is already built for it
- Any farmer tired of stopping to swap covers, bands, or concaves between crops during the busiest weeks of the year
Real Results From Real American Farmers
This isn’t marketing copy. These are the numbers being reported by farmers running XPR3 systems across the United States right now:
| 30% Productivity increase reported by XPR3 users | $300K Annual savings in dockage fees | 20 Days Reduction in wheat harvest window |
It’s no coincidence that all the World Record Yield holders for corn and soybeans have chosen Estes Concaves. When the very best farmers in America need every bushel their land can produce, they don’t gamble on stock equipment.
Feikema Farms — a real-world XPR3 operation — reported their harvesting efficiency improvements were immediate and measurable, with less grain left in the field and a combine that ran harder, longer, and with less downtime than their previous setup.
Built for the Future of American Farming
The combine is evolving. Autonomous systems, AI-guided harvesting, and precision agriculture platforms are changing what it means to run a large-scale grain operation. The XPR3 was engineered with this future in mind.
The patented bar design and no-swap all-crop capability make the XPR3 the only aftermarket concave system ready for fully autonomous combine harvesting — where stopping to change concaves between fields or crops is simply not an option. As automation takes hold, your concave system needs to keep pace. The XPR3 already does.
